Checklist Before Starting the Machine
□ Check the battery power. Charge batteries if power is
below 80%. Brand new batteries should take about 8
hours to charge.
□ Check the condition of the main scrub brushes. Replace
if they are worn out.
□ Check the condition of the rear squeegee and reposition
or replace if it is worn. Always make sure squeegee is
clean before starting.
□ Check the condition of the rubber skirt on the side of the
scrub deck. Reposition or replace as needed.
□ Check that the recovery tank is empty and that floating
filter screen is clean.
Starting the machine
1. Turn the main power key to the ON position.
2. Turn on solution flow (See #3 on Control Panel).
3. Turn on the brushes, then turn on vacuum. (See #7 on
Control Panel).
4. Turn on forward drive. (See #2 on Control Panel).
5. Push accelerator pedal to drive the scrubber forward or
backward. (Warning light and horn will activate when
scrubber is in reverse).
6. Push the brake pedal to stop the machine.
Note:
It is recommended to keep driving speed between
1.5 to 2 miles per hour.
Operating the machine
Warning:
Danger of fire or explosion. Do not use this
machine to pick up flammable or corrosive materials, or
reactive metals.
1. Overlap each scrub pass 3
”.
2. Keep the machine continuously moving, or if you must
stop, turn off brushes, solution flow and vacuum.
Otherwise scrubber may abrade the floor.
3. Squeegee assembly automatically raises when backing
up.
4. If squeegee leaves drag marks on the floor behind the
scrubber, wipe the squeegee to remove dirt. If squee-
gee still leaves drag marks, it may need to be replaced.
Check the condition of the squeegee. If the leading
edge is not square and meeting the ground firmly, it will
need to be repositioned or replaced.
5. Do not operate the machine on inclined surface with
slope exceeding 5% (3°).
6. Please slow down when operating on slopes and
slippery floors, or when turning.
7. If the foam is excessive, add a manufacturer-recom-
mended de-foaming agent into the recovery tank. Follow
the chemical manufacturer-recommended mixing
instructions. Using the wrong chemical or too high a
concentration may cause excessive foam.
Note:
Do not allow foam to enter the filter screen as this
could damage the vacuum motor. The foam may also
cause the filter screen switch to malfunction.
